Solution Overview
Problem
Existing display systems with multiple projectors require complex setup and reconfiguration for cooperative display, leading to significant trouble and cost when changing content.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display systems are arranged to perform cooperative display, then the display effect is improved, but the setting complexity increases
Solution Approach 1:
The display system automatically detects nearby display systems and initiates cooperative display without requiring manual configuration. The system performs self-identification and self-setup, eliminating the need for complex manual setting procedures while enabling cooperative display functionality.
Solution Approach 2:
The system uses proximity detection to sense the presence of other display systems and automatically adjusts its operation accordingly. This feedback mechanism enables the system to adapt its display mode based on the detected environment, transitioning from individual to cooperative display automatically.
2Adaptability or versatility
If multiple display systems are reconfigured for different content, then the display flexibility is improved, but the time and cost increase
Solution Approach 1:
The display system dynamically adapts its configuration based on real-time proximity detection. When content changes are needed, the system automatically adjusts its cooperative display settings without requiring manual reconfiguration, enabling flexible content switching while minimizing reconfiguration time and cost.
Solution Approach 2:
The system performs automatic identification and configuration setup in advance, so when content needs to be changed, the reconfiguration process is already prepared and can be executed quickly without significant time loss or additional cost.
3Area of stationary object
If projection image is enlarged to straddle multiple projection target members, then the visibility is improved, but the detection precision requirement increases
Solution Approach 1:
The system employs an intermediary proximity detection mechanism that indirectly determines the position and orientation of projection target members. This intermediary approach allows the system to achieve the required positioning precision for enlarged straddling projection without requiring extremely high-precision direct measurement of all parameters.

AI summary
A display system having a projector and a projection plate and adapted to project an image from the projector toward the projection plate to thereby display the image includes a proximity detection section adapted to detect a proximity of another display system, which has a projector and a projection plate, and is adapted to project an image from the projector toward the projection plate to thereby display the image, and a control section adapted to determine a projection image, enlarge the projection image determined, and display the projection image enlarged so as to straddle the projection plate and the projection plate of the another display system in a case in which the proximity detection section detects the proximity of the another display system.
